Rear Axle Fluid
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
Axles must have 885 km (500 mi)
before being used in track driving.
The rear axle fluid temperatures
may be higher than when driving in
severe conditions. Drain and refill
Driving and Operating
with new fluid after the first racing or
competitive driving event, and then
after every 24 hours of racing or
competitive driving. See
Recommended Fluids and
Lubricants 0 297.
General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimise engine
performance.
The front license plate bracket or
aero panel should be removed for
track events and competitive driving
to improve engine performance.
If additional brake cooling is
required, the grille mesh in the lower
corners of the front grille in front of
the brake duct can be removed.
This is not reversible, and a
replacement grille will not be
covered by the vehicle warranty.
